NGC 5033 and NGC 5005 With Others

In an attempt to improve my galaxy images I opted to go without a filter and shoot a target that goes directly through the zenith for me. Comparing this to my usual galaxies that use a D1 filter I'm extremely satisfied with the result, however it took quite a bit of work to get here. I ran into an issue with my flats correctly subtracting my vignetting however the subtraction of dust motes would be either "over" corrected or "under corrected" throughout the frame. I ended up stacking this data twice with two different sets of flats: one taken on the night just before imaging against the sky, and one taken against a white-ceiling (both t-shirt flats.) Each would correctly subtract dust motes but only on half of the image. Luckly because of this I was able to leverage the gradient merge mosaic tool to stitch the two stacks together: the halves with the correctly subtracting flats.

Although still some artifacts remain from the work done, I'm glad I was able to pull this off!

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
